RestKit Post Request Issue - ios

Question

Hi I'm trying to post NSManagedObject to the server using Rest Kit. Could somebody take a look and tell me what I'm doing wrong ?
This is my json structure for post request which I tested by using RubyMine REST client and it posted object properly:
{
"name":"test name",
"mobile":"22334455",
"dob":"1989-12-12",
"medications":"test",
"medical_conditions":"",
"watch":
{
"phonewatchno":"123789",
"latitude":-33.99,
"longitude":151.11,
"gmaps":null,
"battery_life":null,
"last_update_time":null,
"location":"",
"short_imei":null,
"rssi":null,
"charging_status":null,
"voltage":null,
"network":null,
"altitude":null,
"ip_addr":null,
"button_press_time":null,
"last_keep_alive":null
}
}
My post method looks like the following one :
id params = #{#"name": #"Tinder",
#"mobile":#"20934920",
#"dob":#"1989-12-12",
#"medications":#"pills",
#"medical_conditions":#"lkas",
#"watch":
#{
#"phonewatchno":#"239847239",
#"latitude":#"-33.99",
#"longitude":#"151.11",
#"gmaps":#"",
#"battery_life":#"",
#"last_update_time":#"",
#"location":#"",
#"short_imei":#"",
#"rssi":#"",
#"charging_status":#"",
#"voltage":#"",
#"network":#"",
#"altitude":#"",
#"ip_addr":#"",
#"button_press_time":#"",
#"last_keep_alive":#""
}
};
RKResponseDescriptor *responseDescr= [RKResponseDescriptor responseDescriptorWithMapping:[MappingProvider myMapping] method:RKRequestMethodPOST pathPattern:#"/myPath.json" keyPath:nil statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
[[RKObjectManager sharedManager]addResponseDescriptor:responseDescr];
[[RKObjectManager sharedManager]setRequestSerializationMIMEType:RKMIMETypeJSON];
[[[RKObjectManager sharedManager]HTTPClient]postPath:#"/myPath.json" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Mapped object %#",responseObject);
[self dismissViewControllerAnimated:YES completion:nil];
} failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
NSLog(#"An error occuered: %#",error);
}];
}
Thanks in advance

You need to create a request descriptor against NSDictionary and then not use the HTTPClient to action the post, just use the object manager (because the client knows nothing about request or response descriptors).
Following your edit your server is throwing an error - check the server log. Your code now looks ok for sending wearers with nested watches and receiving watches and connecting them by foreign key mapping. You need to check exactly what is sent with Charles against what the server is expecting.
